Phoebus, god of Delphi, Locrian Eunomus set up this cicada in your honour, an appropriate symbol of his victory. He was competing in the lyre contest against his rival Sparthys and the strings resounded as he plucked them with the plectrum. A worn string began to buzz with a hoarse rattle and spoil the true melody of the music. Then a sweet-voiced creature, a cicada, flew chirping onto the lyre to supply with its song the broken string. Recruited to follow the rules of musical sound, it flew down from the high glades to bring us aid with its chirping song. Accordingly, so that the honour due to your cicada, o holy god, may last undiminished, on top of the lyre she sits here herself, a minstrel in bronze.
